Definitions

  • the present invention relates to a process for production of a vaccine composi ⁇ tion, the vaccine composition obtainable by this process, a vaccine composition comprising a substrate and an antigen, and the use of a vaccine composition.
  • Vaccine compositions for prevention of viral illnesses for example for prevention of a hepatitis B infection, are known from the prior art.
  • EP-A-O 576 478 describes a vaccine composition based on aluminium salt particles, on whose surface an antigen as well as 3-0-deacetylated monophos- phoryl lipid A (3D-MPL), have been absorbed.
  • EP-A-O 689 454 and EP-A-O 633 784 describe a process for production of a vaccine composition, in which first an antigen and then a 3D-MPL as adjuvant are absorbed on the surface of an aluminium salt particle.
  • the vaccine compositions described in these European patent applications are characterised in that the adjuvant and the antigen are at least partially immobilised in the same aluminium salt particles.
  • WO-A-00/23105 describes an adjuvant composition comprising immune stimulants, which are absorbed at the surface of a metal salt particle, whereby the metal salt particle is substantially free from other antigens.
  • the adjuvant compositions described in this state of the art are obtained in that first the adjuvant is immobi- Used at the surface of an aluminium salt particle and, separately, the antigen is immobilised on the surface of another aluminium salt particle. In order to complete the vaccine composition, the aluminium salt particles are then combined which each other.
  • the vaccine composition described in this international patent application is, accordingly, characterised in that the adjuvant and antigen are im- mobilised on different aluminium salt particles.
  • the disadvantage of the vaccine compositions known from the state of the art consists in that, inter alia, they are characterised by a poor stability.
  • This poor stability of the vaccine compositions consisting of the three components aluminium salt particle, antigen and adjuvant expresses itself, inter alia, in that often a view minutes after the production of the vaccine composition, individual components sediment in the generally liquid preparations.
  • those vaccine compositions in which adjuvant and antigen are immobilised on different aluminium salt particles, such as, for example, the composition which is described in WO-A-00/23105, only have a low immune stimulatory effect.
  • the process described in WO-A-00/23105 requires the use of at least two separate stirring vessels, in which the aluminium salt particle-antigen composition, as well as the aluminium salt particle-adjuvant composition is prepared.
  • a further disadvantage of the vaccine compositions known from the prior art are the often pronounced variations in the immune stimulatory effect of the vaccine compositions between individual production batches.
  • the present invention had the object of overcoming the disadvantages of vaccine compositions known from the prior art, in particular of vaccine compositions for prevention of a hepatitis B illness.
  • the present invention had the object of providing a process for pro- duction of a vaccine composition, which enables the production of a vaccine composition with, to the greatest extent possible, more constant and batch- independent immune stimulatory effect.

Abstract

La présente invention concerne un procédé de production d'une composition vaccinale consistant (i) à obtenir un volume V1 d'une phase aqueuse P1 comprenant un composé d'aluminium dont la surface a été mise en contact avec des ions phosphate, (ii) à obtenir un volume V2 d'une phase aqueuse P2 d'un antigène, et (iii) à ajouter le volume V2 de la phase aqueuse P2 au volume V1 de la phase aqueuse P1 avec agitation du volume V1, l'une au moins, de préférence chacune, des conditions suivantes étant remplie: (a) le composé d'aluminium est chauffé après sa mise en contact avec les ions phosphate et avant l'étape (iii), (b) la phase aqueuse P1 comprend moins de 10 mg/ml d'aluminium, (c) la phase aqueuse P2 comprend moins de 1 mg/ml de l'antigène, et (d) le volume V2 est ajouté à une vitesse d'au moins 10% la quantité du volume V1 par minute au volume V1. L'invention concerne également la composition vaccinale pouvant être obtenue au moyen de ce procédé, une composition vaccinale comprenant un substrat et un antigène ainsi que l'utilisation d'une composition vaccinale.
